[vaxerski]

are you on Hyprland? what ver? Nvidia? 10 bit?

[JojiiOfficial]

Yes hyprland on latest git commit with Nvidia. No 10 bit

[vaxerski]

looks like that one issue with nvidia that requires a patch or something to me.

At any rate, nvidia is not supported.

[realth000]

Maybe here is a workaround?

1. git clone --recursive https://github.com/hyprwm/Hyprland.git
2. Replace function wlr_output_preferred_read_format in wlroots/types/output/render.c like this:

uint32_t wlr_output_preferred_read_format(struct wlr_output *output) {
    return DRM_FORMAT_XRGB8888;
}

Then sudo make install and start Hyprland, both grim and obs works, though not fully tested.

This fixed the issue with obs and grim for me. Thank you.
